VULCAN Pool Heater - Poolstore

ENGLISHThe flow rate of water into the heater must not exceed 17,000 litres perhour (3,740 UK gallons/hour) A higher flow rate will require the installationof a bypass to prevent damage to the heater elements. The heater will notoperate unless the following minimum flow rates are achieved ie:1,000 litres / hour (220 UK gallons/hour) for 3 ~ 6-kW heaters and4,000 litres / hour (880 UK gallons/hour) for 9 ~ 15-kW heaters.Water QualityThe water quality must be within the following limits:PH 6.8 - 8.0TA (Total alkalinity) 80—140ppm (parts per million)Chloride Content MAX: 150 mg/litreFree Chlorine: 2.0 mg/litreTotal Bromine: Max 4.5 mg/litreTDS (Total Dissolved Solids) / Calcium hardness 200— 1,000ppmWater chemistry is complicated if in doubt seek expert advise.Operating Your HeaterUpon completion of the installation, run the water-circulating pump topurge the system & heater of air (i.e. Remove any trapped air in thesystem & heater). TIP: You can encourage air out of the heater flow tube bygently elevating the exit port of the heater when the pump is running.On initial power up of the heater the amber light should illuminate.The heater will only switch ‘On’ (red light indicator illuminated) and theamber light switching ‘Off’ when the following criteria are met ie:• Water circulating pump is ‘On’ delivering in excess of the minimum flowrate of water (see flow requirement information)• Water temperature set point (required temperature) is set to a highervalue than that of the water.6
